This invention relates to improvements in vending machines and has for an object the provision of a coin controlled machine for vending such articles are newspapers,

7 magazines, pamphlets, envelopes, folders,

etc, means being provided for adjusting the ejecting mechanism in accordance with the article being sold.

Another object of the invention is theprovision of a machine of the above character which, in addition'to the above and other advantages, is simple and reliable in construction and use, and may be manufactured at a low cost.

lVith the above and other objects in view, the invention further includes the following novel features and details of construc tion, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

The housing is mounted upon a suitable sold. 5 tion and includes a pair of rear vertically In the drawings V Figure 1 is an elevation of the machine with the front plate removed.

Figure 2 is a sectional view on the line 22 of Figure 1.

Figure 3 is a section on the line 33 of Figure 2.

Figure 4 is an enlarged fragmentary elevation showing one corner of the machine 39 with the front plate removed.

Figure 5 is a sectional view on the line 5-5 of Figure 4.

Figures 6 and 7 are detail sectional views taken respectively on the lines 6-6 and 77 of Figure 1.

base 14.

Positioned within the housing is a magazine which is designed to hold articles to be This magazine is of skeleton formadisposed angle bars or posts and a pair of front vertically disposed spaced angle bars 16. The angle bars 15' are so arranged as to provide stops to hold newspapers or other articles indicated at 17 against rearward movement as well as lateral movement, while the bars 16 act to hold the articles 17 against lateral movement but permit forward movement'of the articles.

Mounted within the housing in upper and lower bearings 18 and 19 respectively are rock shafts 20. These shafts are positioned at opposite sides of the magazine and are rectangular in cross section. Slidingly mounted upon the shafts 20 are collars 21 which carry arms 22 and these arms are provided with elongated slots 23 for the reception of headed pins 24 carried by an ejector plate 25.

Secured to the plate 25 as shown'at 26 m are transversely disposed spaced spring fingers 27 whose outer ends 28 extend below the plate 25. Studs 29 which are carried by and extend upwardly from the plate 25 pass through openings provided inthe" fin- I;

gers 27. Coiled springs 30 mounted upon these studs between the plate 25 and the fingers 27 act to yieldingly force the fingers upward, upward movement of said fingers,

being adjustably' limited by means of thumb nuts 31. By reference to Figure 6 it will be seen that the position of the end 28 of the spring fingers may be regulated by adjusting the nut 31. V In other words, the end 28 of the spring finger may extend below a the plate 25 a distance in accordancewith the thickness of the article to be delivered.

The upper ends of the rock shafts 20 carry beveled gears 32 which are engaged by gears,

33 fastupon a horizontally disposed shaft 34. This last mentioned shaft is mounted in bearings 35 and one of its ends extends through the housing'and has secured thereon an operating crank'36. Thus, by means of thecrank 36, the shaft 34 may be rotated h to rotate the shafts 2O iiropposite directions. This rotation of the shafts 20 will,

through the arms'22, move the plate 25 horizontally, so that the ends 28 of the fingers '27 will engage a newspaper or otherarticle 1% in the magazine and eject the same through the opening 12 onto the tray 13.

Mounted fast upon the shaft 34 is a disk 37 which is provided with a notch 38. Pivotally mounted as shown at 39 adjacent the disk is a latch 10 Whose bill 41 is engageable within the notch 38 to-hold the shaft 34 against rotation. The opposite end of the latch 40 is disposed transversely of the lower end of a coin chute 41-2, while the upper end of this chute is provided with an opening 48 for the insertion of a proper coin. I link 4% has one of its ends pivotallysecured to the disk 37 as shown at 415, while its other end is provided with an elongated slot 46' which receives a pin 47 carried by the latch d0.

lVhen a proper coin is inserted in the opening 43, it will gravitate down the slot 12 and engage the end of the latch 4.0 beneath the slot. The weight of the coin will move the latch to the position shown by the dotted lines at a in Figure 5 so that the disks 87 will be released. The crank handle 36 may then be operated to discharge a paper or other article as previously described. Further rotation of the disk bill end of the latch upward so as to release the coin and permit it to drop into the bottom of the housing.

Secured to the shaft 3 1 is an arm 17 whose outer end has secured thereto one end of a coiled spring 18. The opposite end of this spring is secured to the housing so that when the shaft 34: is rotated, the spring will he tensioned. As soon as the shaft is released, the spring will return the parts to normal position. Tension of the spring may be regulated by adjusting the position of the arm e 8 upon the shaft 3 1 through the medium of a set screw 49.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is:

1. In a vending machine, a housing having a discharge opening therein, means within the housing to support articles in stacked formation, spaced vertically disposed rock shafts within the housing, a horizontally disposed ejector plate, gravity movable arms opcratively connecting the rock shafts and plate to move the latter when the shafts are operated, ejector fingers carried by the plate and having one of their ends extending below said plate to engage the topmost article to be ejected, means to adjust the fingers to regulate the degree of the extended ends in accordance with the thickness of said article, and means to operate the rock shafts.

2. In a vendlng machine, a housing havwill move the In testimony whereof I affix my signature.
